CVE-2015-3196

Status Candidate

Overview

ssl/s3_clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service (race condition and double free) via a crafted ServerKeyExchange message.

Red Hat Security Advisory 2015-2617-01
Posted Dec 14, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-2617-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A NULL pointer derefernce flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacked could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication. A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash.

Ubuntu Security Notice USN-2830-1
Posted Dec 7, 2015
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2830-1 - Guy Leaver discovered that OpenSSL incorrectly handled a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 15.10. Hanno B=C3=B6ck discovered that the OpenSSL Montgomery squaring procedure algorithm may produce incorrect results when being used on x86_64. A remote attacker could possibly use this issue to break encryption. This issue only applied to Ubuntu 15.10. Various other issues were also addressed.

FreeBSD Security Advisory - OpenSSL Issues
Posted Dec 6, 2015
Site security.freebsd.org

FreeBSD Security Advisory - OpenSSL has had multiple vulnerabilities addressed. The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. When presented with a malformed X509_ATTRIBUTE structure, OpenSSL will leak memory. If PSK identity hints are received by a multi-threaded client then the values are incorrectly updated in the parent SSL_CTX structure.
